Factor by Grouping 3m-2n-2nx^4+3mx^4

$3 m - 2 n - 2 n x^{4} + 3 m x^{4}$

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(3 m - 2 n) - 2 n x^{4} + 3 m x^{4}$

Factor out the greatest common factor (GCF) from each group.

$1 (3 m - 2 n) + x^{4} (3 m - 2 n)$

Factor the polynomial by factoring out the greatest common factor, $3 m - 2 n$ .

$(3 m - 2 n) (1 + x^{4})$
